SPLINT-CUTTING MACHlNE.

SPECIFICATION forming part. of Letters Patent No. 311,496, datedFebruary 3, 1885.

Application filed June 1!], 184. (No mode.)

To all whom it may concern.-

Be it known that l, JOHN D. JONES, a citi- Topeka, in the county ofShawnee and State of Kansas, haveinvented certain new and use'fullmprovements in Splint-Cutting Machines and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in theart to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the letters and figures of reference marked thereon, which form apart of this specification.

My invention relates to machines for cutting splints for matches orother uses; and it con sists in the novel construction, combination, andarrangement of the several parts, as will be hereinafter more fullydescribed and claimed.

In the drawings, Figure 1 is a perspective view of my machine. Fig. 2 isa vertical longitudinal section thereof. Fig. 3 is a detail View of thefeed mechanism.

The supporting or main frame is composed of two upright side plates, AA, formedpreferably,with flanged feet, as shown, to facilitate thefastening thereof to the bench or stand.

tween the upper ends ofthe plates, and is provided on one end with thepower-pulleys B, and on the other with a balance or fly wheel, I). Theeccentric b is formed on the middle of the shaft between the plates A A.The plates A A are provided near their frontedges with suitable guidesfor the cross-head O,which supports the cutting-knife c, and has theconnecting rod or pitman b pivotally secured to its upper end, and saidpitrnau is screwthreaded at its opposite end into the eccentricring, sothe length of the stroke may be adjusted as desired. The cross-head O inoperation reciprocates verticallyin the guides of the framing, as willbe understood. An arm, 0 is fixed to the outer side of the cross-head,and projects laterally beyond the frame-plate A, for the purposespresently described. Rollers R R are journaled in the lower edge of themain frame, between the plates thereof, and two corrugated feed-rollers,D D, are journaled one above the other near the outer end of the saidframe, the lower roller, D, being in line with the anti-friction rollersR. The opposite ends of these rollers D D are journaled in yieldingbearings I), (see Fig. 3,) cushioned by rubber or other suitable elasticsubstance, so as to provide for slight variations in the thickness ofthe material in to be cut, the rollers D 1) running on, respectively,the upper and lower sides of such material, as will be understood fromFig. 1. The journals of the rollers D D are extended beyond the sideplate, A, and have secured thereon gears 11 d, meshed together, so saidrollers will be con currently actuated and revolved in oppositedirections, in order to effect the forward feeding of the materialtoward the cutter, in the manner presently more fully set forth. Theextended journal of the roller D is also provided with a ratchet wheelor ring, at, which is engaged by the pallet, presently described, forthe purpose of actuating the feed-rollers D D. A bar, E, is pivoted atits inner end to the side plate, A, and extends thence forward, and hasits opposite end carried in advance of thesaid plate,in position to heengaged on its under side, and raised vertically by the arm 0, extendedlaterally from the cross-head, as before described. The arm E is formedwith a horizontally-elongated slot, 6, about midway its length, and isheld at its outer end in a suitable guide, E. The basebar E ofguideframe E has a set-screw, E turned vertically upward through it, andmay be adjusted above the bar to any proper degree, in order to vary thedistance to which the arm E can fall, and thus regulate the feed of themachine, as will be understood from Fig. 3. The outer end of the arm Eis given a downward tension, preferably by means of a spring, 0, asshown. This spring causes the downward movement of the arm when releasedby the downward stroke of the cross-head. It will be understood that aweight could be used instead of spring 6; or the outer end of arm Ecould be so connected with arm 0' of the crosshead that the latter willgive the arm E a positive downward as well as upward movement; butIprefer to employ the construction shown,and before described. A pallet,F, has its upper end secured to arm E, preferably by means of a boltpassed through the slot 0, so the point of connection may be adjustedalong arm E to vary the length of the stroke of the pallet. The lowerend of this pallet is formed with a clutehj, adapted to engage theratchet-wheel d and revolvethe same on the upstroke ofthepallet. Astop-pawl, f ,is also pivoted to the pallet and engages with the ratchetd",to hold the feed-rollers, and thereby the stock or series of ribbons,in position during the operation of cutting. It is manifest the locationof this stop-pawl might be changed from the pallet to the frame-plate,or said pawl might be dispensed With,though I prefer to use it, as shownand described. A spring, F, connects the pallet with the plate A, so asto hold the clutchf in engagement with the ratchet-ring (1 as will beunderstood from the references.

In the manufacture of my machine I construct the ratchet-ring andfeed-rollers so the number of teeth in the former hear such a relationto the diameter of the feed-rollers D D that one tooth ot' the ratchetis equal the width ofthe splint to be cut, measured on the circumferenceof the feed-rollers.

The material to be split into splints has first been cut into ribbons bythe usual form of veneer-cutting, the grain of the wood running parallelthe width of the ribbons, and this width representing the length of thesplints desired, as will be understood. Anumber of these ribbons areplaced in the frame on the rollers R R, and have their forward endsbrought between and held firmly by the feeddrive-pulley and the shaftmade to revolve,

operating the eccentric, and causing the crosshead to reciprocate in itsguides, cutting the splints with each downstroke, and by means of thelateral arm thereof actuating the arm E and pallet F, engaged with theratchet (V, and thus by the before-described mechanism the blanks arefed forward in position for a new cut of splints, as will beappreciated.

By adjusting the connection of the pallet and its operating-arm thelength of stroke of the pallet an d'the extent of revolution of theratchet may be varied so as to increase or diminish the width of thesplints, as desired.

In Fig. 1 it will be seen the cross-head is shown at about its highestpoint and the bar Ehas been elevated by part 0". Vhen the crosshead isforced downward,the bar E falls, bringing the pointfin position to againengage the teeth of ratchet d. In operation the bar E is always incontact with the part 0*, and rests on said part, being raisedthereby,and lowered when said part c is lowered, as will be understoodfrom the drawings and foregoing description.

Having thus described my invention, what I claim, and desire to secureby Letters Patent,

1. The combination of the cross head, the feed rollers both havingintermeshed gears, and one of said rollers being provided with aratchet-wheel, a pallet adapted at one end to engage the ratchet-wheel,and having its opposite end supported onthe pivoted arm, and the armpivoted at one end, and having its other end operated by the cross-head,sub stantially as and for the purposes specified.

2. The combination of the feed-rollers having theirjonrnals or shaftsprovided with intel-meshed gears, the ratchet-ring secured on. one ofsaid journals, the arm pivoted at one end and extended approximatelyhorizontally along the framing, the cross-head provided within a bar orextension engaged with the said arm, and a pallet depending from saidarm and having a clutch adapted to engage and operate the ratchet-ring,all substantially as and for the purposes set forth.

3. The combination of the cross-head provided with lateral arm orextension 0*, the feed-rollers having their journals extended, andprovided with intermeshed gears, the ratchet-ring secured on one of saidjournals, the arm E, pivoted at its inner end, and having its oppositeend extended in position to be engaged by the bar a", the pendent palletsecured at its upper end to the pivoted arm, and having its opposite endadapted to engage the ratchet-ring,and the springs 6 F,se-

cured at one end to the framing a, and at their base-bar of said frame,substantially as and for the purposes set forth. In testimony whereof Iaffix my signature i presence of two witnesses.

JOHN D. JONES.
